Application filed June 1, 1912. Serial No. 700,987.

To all whom it may concern:

Be it known that I, WILLIAM H. WEEKEN- BERG, a citizen of the United States, residing at Vest Salem, in the county of La Crosse 5 and State of Wisconsin, have invented a new and useful Oil or Grease Gun; and I do hereby declare the following to be a full,

clear, and exact description of the invention, such as-will enableothers skilled in the art to which it appertains to make and. use the same. This invention relates toa newand useful combined-hand oiler or grease gun.

It is the principal aim of this invention to provide a device of this nature, adapted.

mainly for oiling or lubricating inaccessible parts of machinery, or other parts dlsposed at considerable heights, such as the machlne parts of a windmill and the like, andto obl0 tain this result there has been devised a novel form of oiler or grease gun havinga nozzle constructed of replaceable telescopic sections, which are connected together by' threaded bands orv the like, thereby enabling a machinist, or the owner of a wind m1 ll or other machinery or the, like, to reach inac- 'cessible machine parts at considerable hei hts. p

ne of the features ofthe invention is the to provision of'a novel means for operating the plunger for feeding the oil or grease to the. extensible nozzle. v v a Another. feature of the invention is the provision of a handle, which is'inovable' annularly about the circumference of the can, thereby enabling the operatorto move the handle with relation to a lever of the operating mechanism of the, plunger, in order that the'operator may conveniently hold the gun when manipulating the same.

The invention comprises further features and combination of parts, as hereinafterset forth, shown in the drawings and claimed.

In 'the drawings :-Figure 1 is a view in perspective of the improved oil or rease gun constructed in accordance with the in ve'ntion. Fig. 2 is a vertical sectional view through the can, showing the plunger therein in its normal position, prior to forcing the 0 oil ,or grease throu h the nozzle. Fig. 3 is a sectional view on line 3-3 of Fig. 1.

Referring more particularly to the draw-- ings 1 designates the oil or grease can or re;- ceptacle, the top of which is provided with 5 an opening 2 (which is closed by means of a-plug 3) through which the oil or grease ma be deposited in the can.

1 dapted to be moved in the direction of the arrow (1 to force the oil or grease through the nozzle 1, is a plunger 5, to which the plunger rod 6 is connected by threads, as,

shown at.7. This plunger rod 6 operates through a packing or stufling box 8, in the bottom of the can or receptacle. spring 9 1s interposed between the plunger-5 and 'the stuffing box, which assists in forcing the plunger in the direction of the arrow a.

Connected to the lower end of the plunger rodG as at 10 is one end of a lever'll, the substantially central portion of which is fulcrumed as at 12 to a link 13, which in turn is pivoted at 14 between the two ends 15. of the band16, which is annularly movable in the groove 17 adjacent the lower portion or bottom of the can or receptacle. In this manner the operating mechanism of ,the plunger may be adjusted relatively to ,the handle 18, thereby enabling an operator to" conveniently manlpulate the gun. The free end of the lever 11 terminates in a handle 19, whereby the same may be operated. Not only theoperating mechanism is adjustableannularly with relation to the can and the handle 18, but may be held in a fixed p'osition with relation to the can, by tightening the screw 20, which is threaded into the end portions 15 of the band 16. The handle 18 is also movable with relation to the can and the operating mechanism of the plunger.

To obtain this result the bands 21 and 22 are slidableannularly about the can, the band 21 moving in the groove 23 in order to prevent a downward displacement of the same. The portions 24 of the handle 18 are secured or riveted between the ears or end portions 25 and 26 of the bands 21 and 22, by means of the rivets 27 and 28. The groove 17, in v which the band 16 annularly slides prevents upward movement of the band 16.

The nozzle 4 is constructed of a plurality of telescopically united sections 29, firmly held in position with relation to one another by the threaded band 30,'in the manner shown in Fig. 3. The lower section 29 is threaded into an extension 31 of the top of 101.5 the can, as shown. The upper section 32 of the nozzle is curved laterally, as'shown in Fig. .1, in order that an operator ma lubricate inaccessible machine parts, an -owing to the fact that 'the number of sections 290i 1 l l l 5 I the nozzle may be increased or decreased, the nozzle may be shortened or increased in length, so that the operator may reach the machine parts at considerable heights.

From the foregoing it will be noted there has been devised a novel, desirable and convenient oil or grease gun, and one which has been found particularly practical.

The invention having been set forth, what is claimed as new and useful is An oiler or grease gun comprising a can having a nozzle, a plunger operable in the can, an operating mechanism therefor having adjustable connections with the can, the

can having an annular groove adjacent its 1 top, a band slidable in the groove, a second hand slidable annularly about the can below In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses. WILLIAM I-LWEHRENBERG.
